同学你好，很高兴为你解答。
1 but I did't know how to say some food in English，though this class，
didn't拼写错误。
通过这节课，因该是through。though的意思是“虽然，尽管”。这两个词请注意区分。
2  My favorite food are potatoes，broccoli，fish，eggs and chicken
food使用复数foods表示。
3 because they are good for my healthy and it doesn't make me fat.
对我健康有好处，健康用名词，使用health。
and前面是they，后面是it，前后不一致，后面改为they don't make me fat。
4 My favorite drink are honey lemonade and milk
drink改为复数drinks
5 because the milk can give  me protein and honey lemonade was good for my skin，it was also make me refreshing.
honey lemonade was good for my skin改为一般现在时，is good...
后面一句改为it also makes me refreshing.
6 Also I known how to say the prices on price tag，
know的过去式是knew。这里使用一般现在是就好，know。
7  I learned an important word is equal，
去掉is。

祝天天向上~
